How on earth can you get heat out of very cold outside air? How can a heat pump make heat out of cold air?

Through the state change of some very attention-grabbing gases the magic happens.

A heat pump can do some very amazing things on the subject of making heat. To know the way it works you should first perceive what happens when sure gases change from a liquid to a gas and back to a liquid again. To simplify it a bit we will take a look at a primary air conditioning system. The refrigerant in an air conditioning system is changed to a liquid within the outdoor condenser. The compressor compresses the gas forming a sizzling gas. As this gas cools beneath high pressure it adjustments right into a liquid form. Inside the indoor unit the liquid is pushed by a small gap or orifice. When it comes out the other side it quickly modifications to a gas because the pressure abruptly drops. The fast pressure drop changes the refrigerant to a really cool gas. Air flowing over the cool gas inside the pipes makes the air cool and provides air conditioning.

Now for a heat pump the process is far the same. The coils are just switched by used a reversing valve within the outdoor condenser unit. Instead of the heat being discharged to the outside from the condenser unit, the indoor unit turns into the condenser coil. The outside coil now turns into the cold coil and cools the outside. That’s the reason if it is too cold outside the unit should run in air-con mode for a short while to defrost the outside cold coil. During this time the system will usually have electric heat inside to run and hold the indoor air warm.

Now you know that a heat pump is really no more than an air conditioner running in reverse. By means of the magic of utilizing refrigerants a heat pump can run many times more efficiently than straight electric heat.

A careful heat loss/acquire should all the time be performed by a certified particular person earlier than any sizing of a unit. Too large or too small of a heat pump system can cause it to be inefficient and presumably cause it to be very uncomfortable. The longevity of the unit will also be affected by sizing and installation. Be patient and look diligently for the best contractor to install your system.

A properly designed and installed system may give a few years of consolation and efficiency. When you search for and find the fitting contractor to do the job right you will get many hassle free comfortable years out of your heat pump unit.
